Key Facts

Overview

7889 (1994 LX) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1994 LX as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

1994 LX orbits the sun every 518 days (1.42 years), coming as close as 0.82 AU and reaching as far as 1.70 AU from the sun. 1994 LX is about 1.7 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

The rotation of 1994 LX has been observed. It completes a rotation on its axis every 2.74 hours.

1994 LX's spectral type None (Tholen) / V (SMASSII) indicates that it is likely to contain and .

No Close Approaches

1994 LX's orbit is 0.15 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

1994 LX's orbit is determined by observations dating back to Aug. 10, 1977. It was last officially observed on Aug. 11, 2022. The IAU Minor Planet Center records 2,523 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
